IDT74FCT162827AT/CT FAST CMOS 20-BIT BUFFER INDUSTRIAL TEMPERATURE RANGE FAST CMOS IDT74FCT162827AT/CT 20-BIT BUFFER FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT162827T 20-bit buffers are built using advanced dual metal CMOS High-speed, low-power CMOS replacement for ABT functions technology. These 20-bit bus drivers provide high-performance bus interface Typical tSK(o) (Output Skew) < 250ps buffering for wide data/address paths or buses carrying parity. Two pair of Low input and output leakage 1A (max.) NAND-ed output enable controls offer maximum control flexibility and are ESD > 2000V per MIL-STD-883, Method 3015 > 200V using organized to operate the device as two 10-bit buffers or one 20-bit buffer. Flow- machine model (C = 200pF, R = 0) through organization of signal pins simplifies layout. All inputs are designed with VCC = 5V 10% hysteresis for improved noise margin. Balanced Output Drivers (24mA) The FCT162827T has balanced output drive with current limiting resistors. Reduced system switching noise This offers low ground bounce, minimal undershoot, and controlled output fall Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, timesreducing the need for external series terminating resistors. The TA = 25C FCT162827T is a plug-in replacement for the FCT16827T and ABT16827 for Available in SSOP and TSSOP packages on-board interface applications.
